RISAn Improved Slicing Technique for Finite Line Contacts in the Modeling of Rolling Element Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mechanical system often involves the finite line contact of key components such as rolling element bearings and gear pairs. Different contact models have been developed to predict the load–displacement relationship and ...
Coupling of Horizontal, Vertical, and Temporal Resolving Power of a Satellite Temperature Sounder
Publisher: American Meteorological Society
Abstract: Satellite sensor optical systems now provide scan spots that are reasonably small and closely spaced compared with the horizontal scales of atmospheric variability that meteorologists might like to infer. Furthermore, ...
A Fast Calculation Approach for Elastohydrodynamic Finite Line Contacts Applicable to Online Calculations of Rolling Bearing Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite line contacts in rolling element bearings are usually under the regime of elastohydrodynamic lubrication (EHL). To obtain deeper insights into bearing performance, it is necessary to directly couple EHL contact ...
The Ill-posed Nature of the Satellite Temperature Retrieval Problem and the Limits of Retrievability
Publisher: American Meteorological Society
Abstract: The inverse problem of satellite temperature profile retrieval is well known to be ill-posed. Ibis means that not only is a vertical temperature profile solution not unique, but that two solutions can be very different ...
Prediction of Frictional Moment of Cylindrical Roller Bearing Using Experimental Data-Driven Artificial Neural Networks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate prediction of the frictional moment of the bearing contributes to the correct determination of the power loss in drivetrains and the antifriction design of bearings. This paper investigates a method for accurately ...
Dependence of Land Surface Albedo on Solar Zenith Angle: Observations and Model Parameterization
Publisher: American Meteorological Society
Abstract: This study examines the dependence of surface albedo on solar zenith angle (SZA) over snow-free land surfaces using the intensive observations of surface shortwave fluxes made by the U.S. Department of Energy Atmospheric ...
Intersatellite Radiance Biases for the High-Resolution Infrared Radiation Sounders (HIRS) on board NOAA-15, -16, and -17 from Simultaneous Nadir Observations
Publisher: American Meteorological Society
Abstract: Intersatellite radiance comparisons for the 19 infrared channels of the High-Resolution Infrared Radiation Sounders (HIRS) on board NOAA-15, -16, and -17 are performed with simultaneous nadir observations at the orbital ...
Coupling a Markov Chain and Support Vector Machine for At-Site Downscaling of Daily Precipitation
Publisher: American Meteorological Society
Abstract: AbstractStatistical downscaling is useful for managing scale and resolution problems in outputs from global climate models (GCMs) for climate change impact studies. To improve downscaling of precipitation occurrence, this ...
Comparison of an Experimental NOAA AVHRR Cloud Dataset with Other Observed and Forecast Cloud Datasets
Publisher: American Meteorological Society
Abstract: CLAVR [cloud from AVHRR (Advanced Very High Resolution Radiometer)] is a global cloud dataset under development at NOAA/NESDIS (National Environmental Satellite, Data, and Information Service). Total cloud amount from two ...
Evaluation of the Earth Radiation Budget in NCEP–NCAR Reanalysis with ERBE
Publisher: American Meteorological Society
Abstract: This study presents an evaluation of the NCEP?NCAR Reanalysis (the reanalysis) by comparing its components of the earth radiation budget to satellite data. Monthly mean clear sky (CS) and total sky of outgoing longwave ...
